Application flled 'February 2, 1988. Serial No. 616,588.

To all 'whom it may concem:

Be it known' that I, CHARLES L. BnAmY, a citizen of the United States,residing at Chicago, county of Cook, State of Illinois, have inventedcertain new and useful Improvements in Laundry Driers, of which thefollowing is a specification.

This invention relates to improvements in laundry driers.

The main objects of the invention are:

First, to provide an improved laundry drier by means of which laundrymay be very rapidly dried 'and treated with cold fresh air.

Second, to provide an improved laundry drier which is of large capacityand simple and compact in structure.

Third, to provide an improved laundry drier inwhich the dried articlesare sub.- jected to but little wear.

Fourth, to provide an improved laundr drier whichl producessubstantially the e fects of open air drying.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish'the objects of my invention byv the devices and meansdescribed in the following specification. The invention is clearlydefined "and pointed out in the claims.

A structure which is' apreferred embodiment of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisapplication, in which: i

Fig. I is a frontelevation of a structure embodying the features of myinvention, parts being shown conventionally and parts being sectionedand broken away ;for convenience in illustration.

Fig. II'is 'an end view looking from the left of Fig. I with partsbroken away for convenience in illustration.

Fig. III is a transverse section on a line corresponding to line 3-3 ofFig. I.

Fig. IV is a front elevation partially in 'Vertical central longitudinalsection of a modified form or embodiment'of my invention.

In the drawing similar reference numerals refer to similar partsthroughout the several views.

Referring to the drawing, I provide a. cylindrical casing 1 mounted uponsuitable standards 2 and having a door 3,| the casing when the door isclosed being substantially an alr-tlght casing. Within this casing is adrylng cylmder 4 having a side door 5 and end walls 6. In the preferredembodi-' i rsiderable size it is preferably provided with foraminatepartitions 9.

At the bottom of the casing is an air open- .mg 10 connected by theconduit 11 to the blower 12. This blower is connected to the heater 13,there being a cold air passage or conduit 14 Controlled by the gatevalve 15 so that either 'heated or cold air .may be dehvered by means ofthe blower 12.

I also preferably provide a blower 16 which is connected by the conduits17 to the tubular bearings 8 although, if desired, either one of theseblowers 'may be omitted with satisfactory results or either one may -becut out of operation, if desired.

' The drying cylinder is driven from the motor 18, the driving shaft ofwhich is prof vided with a pinion 19 meshing with a gear 20 whichinfiturn meshes with the gear l21 secured to the drying cylinder.` Thisdrives the cylinder at a relatively low speed. I

preferably p'rovide gasket or packing members 22 which are disposed in aspaced relaton' longitudinally of the casi'ng to coact with thecylinder, providing a longitudinal passage 23 into which the conduit 1.1opens. These packing or gasket members 22 confining the air within thispassage compels it to pass upwardly through the lower portion of thecylinder or outwardly therethroughacair to ass upwardly or downwardlyaround the cy inder. In vany event, with this ar- 'cording to thedirection of the current of i rangement of conduits, the one openingwithin, the cylinder 'and the other,- within the casing, the air mustpass through the cylinder and is eflFectiveIy brought into con' taetwith the articles as 'they are gentiy tumbled or stirred about bythe'rotationof the casing.

In the modified form of my inventlon shown in Fig. IV the blower 24 isconnected with the heater 25 and to the cylinder througha tubularjournal and the 'tubular bearing ofthe character shown in Fig. I, theother journal 26 being a solid journal.

The air conduit 27 is connected tothe end of the casing opposite thetubular journal so that the air is compelled to pass through thecylinder. In this modification the blower may be reversed and the airwould pass in the opposite direction.

My improved drier is of very large capacity. The laundry is rapidly andefl'ectively dried and has the fresh attractive quality of laundry driedin the open a1r.

I have illustrated and described my improvements in embodiments which Iregard as very satisfactory. I have not attempted to illustrate ordescribe various other embodiments or adaptations which Ilcontemplate'as I believe the disclosure made will enable those skilledin the art to which my invention relates to embody or adapt the same asmay be desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. In a laundry drier, the combination of a cylindrical casing providedwith tubular bearings, a drying cylinder having a foraminate peripheralwall and having tubular journals coacting With said tubular bearingsproviding air passages opening to the interior of the drying cylinder,said drying cylinder having spaced transverse foraminate partitionstherein, members disposed longitudinally of said casing to coact withsaid cylinder providing a longitudinal air passage below the same, airconduits connected to said tubular bearings, an air conduit connected tosaid air passage at the bottom of' said casing, meansl for driving saidcylinder, and blowers for circulating air through said conduits, allcoacting for the purpose specified.

2. In a laundry drier, the combination of a casing, a drying cylinderhaving a foraminate peripheral Wall and having tubular journalsproviding air passages opening to the interior of the drying cylinder,members disposed longitudinally of said casing at each side of saidinlet to coact with the periphery of said cylinder providing alongitudinal air passage below said cylinder, air conduits connected tosaid tubular bearings, an .air conduit connected to said air passages atthe bottom of said casing, means for driving said cylinder, and a blowerconnected to one of said conduits so that the air is caused to passthrough said cylinder.

3. In a laundry drier, the combination of a closed cylindrical casing, adrying cylinder having a foraminate peripheral wall and a tubularjournal opening wlthin the cylinder, members disposed longitudinally ofthe casing to coact with the cylinder providing a longitudinal aircirculating passage of which the cylinder constitutes the inner wall,and air circulating means connected to deliver to said passage anddischarge through the journal.

4. In a laundry'drier, the combination of a casing, a foraminatecylinder rotatably mounted within said casing, an air passage opening tosaid cylinder axially thereof, members disposed longitudinally of thecas- 'ing coacting with the cylinder providing a longitudinal airpassage of which the cylinder constitutes the inner wall, and a blowerconnected to one of said passages so that the air passes through saidvcylinder to escape by the other passage.

5. In a laundry drier, the combination of a casing, a drying cylinderhaving a foraminate peripheral wall and having tubular journalsproviding air passages opening to the interior of the drying cylinder,said drying cylinder having spaced transverse foraminate partitionstherein, air conduits connected to said .tubular bearings, an airconduit connected to the bottom of said casing, means for driving saidcylinder, and an air circulating means connected to one of saidconduits, all coacting for the purpose specified.

In witness whereof, I have hereunto set my hand and seal.
